I don't remember if you can shrink a DISK pool with DELETE VOLUME or not. I
think so, but I won't swear to it.

Most people use DISK for short-term storage (overnight, typically) so they
don't have to wait for the tape drives to keep up with incoming traffic and
use FILE for longer-term storage; FILE is a relatively recent addition to
TSM (last decade or so :-) ) that I presume you're using for your long term
storage. If that's the case, I'm sure you can DELETE VOLUME on empty
volumes to recover some of that space so you can use it for the active
pool. Alternately, migrate all the primary data to tape (the new ONSITE
pool!) so they're all empty. Restores would be relatively slow until you
populate the active pool, but that might not be noticeable to anyone.

Others probably have better ideas than me, but I wanted to speak up so you
didn't cling too long to some misconceptions. (I'm no longer an active TSM
administrator, so double-check all of my ideas before rushing too far too
quickly.)
